OpenSim

Lower Limb Model 2010
Model of the lower limb based on experimental measurements of muscle architecture in 21 cadavers. The model provides accurate representations of muscle moment arms and force generation capacities and allows detailed examination of the moment generation capacities of muscles about the ankle, knee, and hip.

Upper Extremity ModelFifteen degree-of-freedom model of the human upper extremity that has the strength of a young, adult male and includes the lines of action of fifty muscle-tendon actuators. The model includes the kinematics of the shoulder, elbow, forearm, wrist, thumb, and forefinger.

Generic Lower Extremity Model Seven degree-of-freedom model of the human lower extremity
that has the strength of a young, adult male and includes the lines
of action of forty-three muscle-tendon actuators. The model includes the kinematics
of the hip, knee, ankle, subtalar, and proximal metatarsal joints.

Deformable Lower Extremity Model
Four degree-of-freedom model of the human lower extremity with a "deformable" femur that characterizes the geometry of the pelvis, femur, and proximal tibia, the kinematics of the hip and tibiofemoral joints, and the paths of the medial hamstrings, iliopsoas, and adductor muscles for an average-sized adult male.
